Cool how you guys bring up your single speaker rigs just as I'm coming to the conclusion that I think I prefer single speakers these days. I never used to, but I think I do now. It took a long time to get used to it because I equate bass with big (or at least medium), but when I use a single speaker, my sound is way more even across the stage, and it moves plenty enough air to make me quite happy.
I've been trying to adhere more closely to things Bill FM says about sound onstage, and the more I do what he says, the better it keeps sounding to me. My main rig used to be a Mini CMD121P on a B-15 cab, but now I'm alternating between my Mini CMD121P by itself or a B-15 by itself. It's funny...I used to not care about any of this audiophile crap like comb filtering and phasing and beaming and all that, and now I'm realizing it's all a major reason I haven't ever been completely happy with my live sound. At first I thought the Markbass combo sounded a little thin by itself, but angling it up toward my head and rolling off excess highs with the VLE fattens it up and tames that piezo down. So maybe there is something to that audiophile crap after all
